The P90 is the most expensive SMG in the game, at $52,500.

It's also very accurate and powerful at close to mid range. Its shooting profile allows it to reliably and safely eliminate zombies with precise headshots.


Try to get the crits last. AP rounds and reload speed are most important.

  • As the P90 has a very high crit chance when maxed, it may be a good idea to use crit perks with the P90.
  • The Akimbo and Critical Aim upgrades are conflicting upgrades, meaning once you buy one you are locked from buying the other. This is to prevent the Critical Aim upgrade from becoming useless as Akimbo weapons lose their ability to ADS and therefore cannot benefit from it.


  • Unlike the other SMGs, the P90 uses ammunition (5.7 x 28 mm) that is shaped like that used in rifles.
